What's this sound on this track? Bird or equipment fault?

["Peter Shute" pshute2]

I recorded the sound of a quail being flushed, and there's this odd, very b=
rief squeak in the recording. I don't know if it's the bird, or if it's som=
e sound that I or the equipment made. One theory is that as I quickly swung=
 the microphone to follow the bird, the rubber bands of the shock mount str=
etched and squeaked.

But it also sounds a bit like the recorder just stopped recording for an in=
stant, maybe a loose cable?

The recording is here:

The sound can be heard during the wing beats as the bird flushes, and I've =
marked the spot with a comment. Any opinions?
